Abstract

Un aparato de desviación incluye un amplificador de desviación acoplado con un circuito de modulación de forma de onda de desviación, tal como un modulador de diodo. Una fuente para generar una señal de modulación. La señal de modulación incluye un componente de corriente alterna periódico simétrico que tiene primera parte del período de rastreo. Un amplificador de retroalimentación altera la amplitud de una primera parte del período de rastreo, para hacer al componente de corriente alterna asimétrico. El componente de corriente alterna asimétrico se acopla con el circuito de modulación de forma de onda de desviación, para la modulación de forma de onda de desviación.A deflection apparatus includes a deflection amplifier coupled with a deflection waveform modulation circuit, such as a diode modulator. A source to generate a modulation signal. The modulation signal includes a symmetric periodic alternating current component that has the first part of the tracking period. A feedback amplifier alters the amplitude of a first part of the tracking period, to make the AC component asymmetric. The asymmetric alternating current component is coupled with the deflection waveform modulation circuit, for deflection waveform modulation.
